Pat, haven’t been able to get my pal to print the vinyl for me yet, so I have made up a mini f22 and covered it with some spare vinyl I had left from the van. It weighed in at 6.3 oz before the vinyl and is now 7.1oz with the vinyl on it … do you think this is a bit heavy??

Lockey

Nope! I took a bare one and put LEDs on it. It went from 6.5oz AUW to 7.5oz AUW and flies just fine!

Well, I finally broke down and tried an 800mAh 3S on mine (I've been flying 450's).

And, as much as I hate hate hate to add weight to an airplane that already flies well, I have to admit that it flew great with the 800. You can certainly feel the extra weight, especially at low speeds, but it had more oomph and penetrated better. Landings were less floaty but, all-in-all, probably actually easier than with the 450's. The plane has less of a tendency to just stop dead in the air at the wrong moment.
